| PRELIMINARY DATA SHEET C to KU BAND SUPER LOW NOISE AMPLIFIER N-CHANNEL HJ-FET FEATURES * SUPER LOW NOISE FIGURE: 0.60 dB TYP at 12 GHz Noise Figure, NF (dB) NE425S01 NOISE FIGURE & ASSOCIATED GAIN vs. FREQUENCY 24 VDS = 2 V ID = 10 mA * GATE LENGTH: 0.20 m * GATE WIDTH: 200 m * LOW COST PLASTIC PACKAGE Ga 16 1.0 12 DESCRIPTION The NE425S01 is a Hetero-Junction FET that utilizes the hetero junction to create high mobility electrons. Its excellent low noise and high associated gain make it suitable for DBS and other commercial applications. NEC's stringent quality assurance and test procedures assure the highest reliability and performance. 0.5 NF 0 1 2 4 6 8 10 14 20 8 4 30 Frequency, f (GHz) RECOMMENDED OPERATING CONDITIONS (TA = 25C) SYMBOLS VDS ID Pin CHARACTERISTICS Drain to Source Voltage Drain Current Input Power UNITS MIN TYP MAX V mA dBm 2 10 3 20 0 ELECTRICAL CHARACTERISTICS (TA = 25C) NE425S01 S01 UNITS dB dB mS mA V A 10.5 45 20 -0.2 MIN TYP 0.60 12.0 60 60 -0.7 0.5 90 -2.0 10 MAX 0.80 PART NUMBER PACKAGE OUTLINE SYMBOLS NF1 GA1 gm IDSS VGS(off) IGSO PARAMETERS AND CONDITIONS Noise Figure, VDS = 2 V, ID = 10 mA, f = 12 GHz Associated Gain, VDS = 2 V, ID = 10 mA, f = 12 GHz Transconductance, VDS = 2 V, ID = 10 mA Saturated Drain Current, VDS = 2 V, VGS = 0 V Gate to Source Cutoff Voltage, VDS = 2 V, ID = 100 A Gate to Source Leak Current, VGS = -3 V Note: 1. Typical values of noise figures and associated gain are those obtained when 50% of the devices from a large number of lots were individually measured in a circuit with the input individually tuned to obtain the minimum value. Maximum values are criteria established on the production line as a "go-no-go" screening tuned for the "generic" type but not each specimen.
